A Lightweight Java Taskspaces Framework for Scientific Computing on Computational Grids

A prototype Taskspaces framework for grid computing of scientific computing problems that require intertask communication is presented. The Taskspaces framework is characterized by three major design choices: decentralization provided by an underlying tuple space concept, enhanced direct communication between tasks by means of a communication tuple space distributed over the...

A Middleware for Constructing Highly Available, Fault Tolerant, and Attack Tolerant Services

This paper describes the design of a middleware that provides support for constructing highly available, secure, fault-tolerant, and attack-tolerant services. The central component of this middleware is a group communication service that comprises of six network protocols: atomic broadcast, group membership, failure detection, attack detection, group access control, and secure...

Discovering Documentation for Java Container Classes

Modern programs make extensive use of reusable software libraries. Given the extensive code reuse in Java programs, it is important for the reusable interfaces to have clear and unambiguous documentation. Unfortunately, most documentation is expressed in English, and therefore does not always satisfy these requirements. Worse yet, there is no...

Potential Cognitive Radio Denial-of-Service Vulnerabilities and Protection Countermeasures: A Multi-Dimensional Analysis and Assessment

Cognitive radios sense spectrum activity and apply spectrum policies in order to make decisions on when and in what bands they may communicate. These activities go beyond what is done when traditional radios communicate. This paper examines the denial of service vulnerabilities that are opened by these additional activities and...

An Evaluation of Fault Tolerant TCP-Splice Based Web Server Architectures

TCP splicing has been commonly used for increasing the performance of serving web content through proxies. Web server architectures built using TCP splicing suffer from two limitations: all traffic between clients and servers typically passes through the proxy, thus making the proxy scalability and performance bottlenecks; and this architecture cannot...

Jamming and Sensing of Encrypted Wireless Ad Hoc Networks

This paper considers the problem of an attacker disrupting an encrypted victim wireless ad hoc network through jamming. Jamming is broken down into layers and this paper focuses on jamming at the Transport/Network layer. Jamming at this layer exploits AODV and TCP protocols and is shown to be very effective...
